RFM Series Installation General Installation Guidelines
This manual covers basic installation and wiring for the RFM Series Antennas. Before
installing, check with the vehicle manufacture for recommended hardware and attachment
procedures for securing the antenna to the roof.
!!! Important !!! This Antenna System should only be installed by a certified or trained
technician(s). The technician should be familiar with installation of mobile
satellite antennas and procedures for installation on similar vehicles.
Installation of a RFM Antenna requires 2 technicians and should be performed
in a facility where a Hoist, Crane or Fork Lift is available!

➢ Unpacking
Remove 14 wood screws with flat washers around the base of the cardboard box that is
attached to the wood pallet. The cardboard box will lift up and off of the Pallet.
Inside the RFM Mount Box is the Mount Assembly (1.2M or 98CM), the Mounting Pan
(secured to the Pallet), the Feed Glide Plate, 30’ Antenna Control Cable (attached to
connector box), Antenna Controller Box (includes antenna controller and power supply).
Also included is the Antenna mounting hardware usually wrapped against one of the dish
mounting arms.
The Antenna Mount Assembly weighs about 150 Lbs. (68Kgs). Depending on equipment
available, keep the Mount Assembly attached to the Pallet until it is ready to attach to the
Roof or other surface. Moving the Pallet/Mount Assembly to the roof is recommended.
The system usually ships with 2 boxes. The second box contains the Antenna Reflector.
To protect the Antenna leave it inside the box until it is ready to be attached to the
Mount Assembly that is securely attached to the roof.

➢ Handling the Mount Assembly This Mount Assembly has multiple PINCH and CUT points that during
installation and operation can result in severe injuries. There are hinging and
moving parts that move during installation that can fall due to gravity.
Become familiar with the antenna before installation and insure that everyone
working around this antenna is aware and alert of the dangers associated
during installation and operation!
When working around the RFM Antenna it is important to know the position of the Feed
Arm Assembly. Use Bungee Cords to secure the Feed Arm to the Dish or Dish Arms while
working on the Dish Mount.

➢ Attaching to Roof (Dish Mount installation) It is not necessary to raise the Dish Arms when securing the Dish Mount to the Vehicle or
Trailer. The Mounting Plate comes with pre-drilled holes and slots for convenience. It is
OK to drill other holes in the mounting plate for installation.
The Dish Mount includes a Feed Stow Plate that can be placed in an ideal position to allow
for the Feed Assembly to touch and slide on the roof surface. This can be secured after
the stow is tested and the Feed slides completely on the plate.
The Mounting Plate is designed so the Connector Box can be placed on either side to
simplify wiring.
When installed on a vehicle the
dish will have a rotational radius
of about 52” from the center of
the Mount Base when the system
is searching for a Satellite that
has an elevation of about 10
degrees of the horizon.
In extreme northern or southern
parts of the world the clearance
required may be even less.
The Mounting Pan is 48” x 23”
(7.7 Sq. Ft Area).
5
The Dish Mount with a 1.2M Antenna and Feed Assembly weigh approximately 180 Lbs.
Attached to the Mounting Pan the dispersed weight is about 24 Lbs. per Sq. Ft when
installed on the vehicle. As part of the total Dish weight a Deployed Antenna wind loading
must be included.
Deployed Survival rating on a 1.2M Antenna in 60 MPH wind is about 180 lbs. plus the
system weight of 180 lbs. = 360 Lbs. / 7.7 Sq. Ft now equals about 48 Lbs. per Sq. Ft.
Wind Speed Wind Load on Dish Total Stress Load on Roof
40 mph 59 lbf 26 Lbs Sq Ft 50 mph 92 lbf 41 Lbs Sq Ft 60 mph 133 lbf 59 Lbs Sq Ft 80 mph 235 lbf 104 Lbs Sq Ft
If the vehicle installation requires deployed survival wind speeds of up to 80mph (129 kph)
the minimum required roof (stress) load is 104 Lbs Sq Ft (4.4 Kg Sq M). We recommend
doubling the Roof Loading values in insure a solid safe installation.
Use the chart above to determine the customer requirements. Operational requirements
are typically 30% to 50% lower.
Confirm with the vehicle manufacturer the maximum roof loading in Lbs. Sq. Ft. These are
wind survival requirements and not operational requirements. Also consider that even if a
roof can support 210 Lbs Sq Ft, if the hardware to attach the antenna to the roof is not
secured properly to the roof structure the wind survival rating may not be sufficient.
For more information, see Wind Loading Illustrations and additional mechanical detail at
the end of this document.
Use a Lap Sealant to help secure the Mounting Pan to the Roof.
6
Using a Lap Sealant (Dicor 501LSG or Equiv.) will add additional bonding to the vehicle
surface. Running a bead of this sealant lengthwise along the bottom edges of the mounting
plate and 2 beads through the center lengths of the plate is recommended when possible.
Remember once this sealant has cured removal of this plate will be difficult.
Check with the vehicle Manufacture to determine recommended type of hardware to use
for securing the Dish Mount/Dish Pan to the Vehicle. Use a minimum of 6 screws on both
sides of the mounting plate in the slotted holes. Use at least four screws on both sides of
the Dish Mount AZ/EL Base. Use sealant where required (in drill/screw holes) to prevent
water leaks through the roof.
The Feed Stow Plate is used only as a protector to the roof surface. It can be secured
with 4 short self-tapping screws and water proof sealant (Dicor or similar) to prevent
leaking. If putting any sealant under the Stow Plate use it sparingly in case adjustment is
necessary.
NOTE: Before using Lap Sealant on any exposed screws or holes you should finish
the installation of the Antenna and complete wiring to avoid inadvertent contact and
tracking of the sealant (on clothes and inside customer’s vehicle) making this a cleaner
installation.
➢ Wiring (Dish Mount Connector Box) Note: Before Installing the Dish Reflector (parabolic antenna) to the Antenna Mount
it will be easier to complete the system Wiring. Prewiring the Antenna will allow you
to raise the Dish Arms to make installation of the Dish easier.
If you choose to install the Dish Reflector before completing the system wiring you
can skip wiring and go to Installing the Dish Reflector below.
The RFM Antenna System usually comes with the BUC and LNB prewired to the Feed Horn
Assembly.
The RF (Coax) cabling is wired from the Feed Assembly to the Connector Box located on
the Base Mounting Plate. The Black Coax is the Receive cable connected to the LNB and
the cable is usually labeled with RX at the Base. The White Coax is the Transmit cable
connected to a BUC (Block Up Convertor) or an HPA (High Powered Amplifier).
In addition to the Coax Cables the Mount is also prewired with a 12 conductor control
cable which connects to motors, sensors and GPS modules.

Run the Antenna Control Cable and the Coax Cables from the Roof though the roof entry
box to the Electronics compartment.
Place the Antenna Controller near other associated electronics (router, modem) and make
necessary connections for proper operation.
The DataSAT ACU-2 1RU Antenna Controller has five connections on the rear panel.

With Basic wiring complete you can use the DataSAT ACU-2 Antenna Controller to
manually move the Antenna Elevation into a raised position to Install the Dish Reflector.
Use the Menu, Search (Up) and Stow (Down) buttons on the front panel to access Move EL
functions. The Up Button will raise the Antenna manually when in the correct mode. Raise
the Dish Arms to about 60 degrees UP direction to simplify Dish Installation.
See the DataSAT ACU-2 Manual for detailed information.

➢ Installing the Dish Reflector (Antenna) If you choose to install the Dish Reflector before completing the system wiring it is
still easier to use the supplied 30’ Antenna Control Cable that comes attached to the
Dish Mount to manually raise the Dish Arms using a tool Battery or the supplied 24
Volt DC Power Supply.
Remove the Red and Orange wires that are connected to the 12 Position Euro Style
Connector. These wires will raise and lower the Elevation Motor only.
Touch one wire to the positive and one wire to the negative sides of the battery or the 24
VDC power supply and check the direction of the Elevation Dish Arms. If you hear the
Elevation Motors stalling then reverse the wires and test again.
Raise the Antenna manually until the Dish Arms are about 60 degrees UP direction to
simplify Dish Installation.
With the mount tilted back at this angle it will be easier to place the Dish Reflector onto
the Dish Arms.
Dish Hardware is usually wrapped up against one of the Dish Arms. This hardware
includes; 2 each – 5/16” x 3 1/2” Button Head Socket Cap Screw, 2 each – 5/16” x 2 3/4”
Button Head Socket Cap Screw, 4 each 5/16” Flat Washer, 3 each - 1/4” x 1 1/4” Socket
Head Cap Screw, 3 each – 1/4” Flat Washer, 1 each 1/4” x 1” Fender Washer. All Stainless
Steel. Also included is an 3/8” T x 12 3/4” L Aluminum Dish Base Bracket (T Bar).
Remove the Dish Reflector (Antenna) from the Dish Box (Box #2).

With the Dish Reflector properly attached to the Antenna Mount and all procedures above completed
the system is ready for final wiring inside the Vehicle and system testing.
Use the DataSAT ACU-2 Controller Wiring-Configuration-Operation Manual to complete the installation.
After completion of system wiring before moving the Antenna automatically one technician should
remain outside with a clear view of the Antenna and watch the Antenna Mount perform a Dish
Calibration. Check that the Antenna clears all roof objects and is secured to the roof.
When all tests are complete you should perform a final inspection of the roof installation, and then
apply the roof sealant (Dicor) on any exposed or open screws and roof holes.
Look for any loose tools or hardware before leaving the roof installation.
